To all whom it mayconcem: a embodiment -of the invention, but it is to be Be it known that I, EDWARD H. KoKnN, a understood that changes, variations and citizen of the United States, residing at modifications can be resorted to which come Akron, in the county-of Summit and State within the scope of the claims hereunto ap- 5 of Ohio, have invented new and useful Im pended.

The cont-ractingor Referring to the drawings in detail the compressingof the base also serving to prereference numeral 1 denotes tl1ef elly,mount' Vent the unintentional displacement of the ed on which is a folly-rim 2 with the side 2 tire and the danger of its being torn from faces 3 thereof beveled or inclined and roits position on the rim. jecting laterally slightly over the side aces The invention contemplates providing the of the felly 1. This rim is preferably endfellywith a rim constituting a seat or a less and is shrunk or otherwise secured on tire, the inner lateral faces of which are bevthe felly l in such a manner as to prevent z5 eled.

This tire may have any transversely toward the tire the bands will tread formation and may be continuous, ancontract and simultaneously engage the side nular, or may be made up of a plurality of edges of the base of the tire to contract the independent blocks.

In ably placed within the base portion of the-. order to movethe tire-retaining bands trans. tire a plurality of transversely extending versely toward each other there is provided rods 9 extending into the lateral ribs 7 but a pair of rings adapted to be held in position preferably terminating short of the side by means of bolts extending through them edges thereof. The transverse diameter of 9 and the body of the folly to draw them in,- the base portion of the tire will preferably, .5 wardly toward the side faces of the latter under ordinary circumstances, be wider than for forcing the tire-holding bands inwardly the outer face of the felly-rim 2. against the felly-rim and thetirebody. The The tire 4 is preferably held in position on effect of which is to compress the base of the the felly-rim 2 by means of a pair of con-- 3 tire to render the latter more compact and tractible tire-retaining bands, eachconsist-- ,firmer, thereby eliminating the danger of ing of a split-ring 10, each of which em- "creeping and stiffening and strengthening bodies an outer portion 11 which is hookthe tire structure. I shaped to engage one shoulder 8 of the tire.

With the foregoing and other objects in The lateral outer-face 12 of each of the view, the invention consists in the novel con bands is preferably flat and the inner porstruction, combination and arrangement of tion 13 is wedge-shaped with the opposite parts constituting the invention. to be herelateral face 14 inclined to enga e the in inafter specifically described and illustrated clined face 3 on one side of the elly-rim 2 in the, accompanying drawings which form and is complemental thereto. Between the a part hereof wherein is shown the preferred. inclined face 14 and the hook-shaped por tion 11 of these bands are contracted neck portions. These contractible tire-retaining bands 10 are adapted to be positioned on opposite sides of the tire with the hook portions 11 disposed opposite to the, shoulders 8 of the tire and with the inclined faces 14 thereof arranged in engaging relationwith the lateraly inclined faces 3 of the fellyrim 2. y

The tire-retaining bands 10 are moved toward each other and into engagement with the lateral faces of the'tire by-the fol-- lowing mechanism. 'Mounted on the sides of the felly are a pair of clamping rings 15 each of which embodies an outwardlyprojecting flange 16 adapted to bear against the outer face of one of the tire-retaining rings 10, from which extends laterally toward the felly a horizontal portion 17 the outer face of which constitutes a seat for one of the members 10 when'the parts are assembled. Extending inwardly from the portion 17 is a flange 18 which is adapted to abut against one of the sidefaces of the felly, and these clamping rings are provided with alined apertures to receive bolts 19 which also extend through the felly and bear nuts 20 by which the clamping rings are drawn toward each other to bring the flanges 18 snugly against the felly when the tire is set up.

It will be noted from the foregoing construction that as the bolts 19 are tightened up the outwardly-projecting flanges 16 engage the outer lateral faces of the contractible tire-retaining bands 10 forcing them inwardly toward each other and as their inclined faces 14 engage the inclined-lateral faces 3 of the felly-rim' it will cause them to contract circumferentially as they move toward each other, in doing, which the hook-portion 11 of the tire-retaining bands engage the shoulders 8 of the tire forcing the base portion of the tire. inwardly under considerable tension and simultaneously compressing the same laterally until a tiro whichhas approximately the natural configuration shown in Fig. 2 will be distorted into the shape shown in Fig. 1. This distortion of the base portion of the tire tends to compact or compress it, making the same denser and accomplishing theobject sought by this invention.

Itwill be particularlynoted that as the tire-retaining b ands 10.are split ringswith laterally-inclined faces which engage laterally-inclined faces of the felly--"rim, any in- Ward transverse movement given to them toward each other will naturally cause a contraction thereof by means of the wedging action set up by the contact of their inclined portions with the inclined faces of the folly rim; and as the compacting or compression pf the base portion of an elastic vehicle tire is acpo named by exceedingly favorable results in the use of this type of tire, the object sought is easily effected by the means hereinbefore described.

I claim:

' 1. A vehicle wheel embodying a circumferential rim having the lateral faces thereof inwardly beveled, the outer face of said rim constituting a tire seat, a pair of tireretaining bands comprising split rings posi-' tioned on opposite sides of said rim, the outer portions of said bands formed to engage the base portion of a tire and their inner lateral port-ions beveled to engage the beveled side faces of said rim whereby when said bands are forced transversely toward each other the beveled portions of said bands and'rim will engage causing thereby a contraction of the former, and a pair of annular clamping bands arranged to engage the outer lateral faces of said retaining bands. for drawing the latter toward each other and simultaneously contracting the same on said tire.

'2. vehicle wheel embodying a tireseating circumferential rim having the lat ,eral faces thereof inwardly beveled, a pair of tire-retaining bands comprising broken -rings positioned on opposite sides of said rim, the outer portions of saidebands suitably formed to engage the base portion of a tire and \Vltl'lj' their inner lateral portionsbeveled to engage the beveled side faces of said rim whereby when said bands are shifted transversely toward said tire the beveled portions of said bands and rim will engage causing thereby a contraction of the former and a simultaneous compression of the base portion of the tire and means independent of said bands and rim-for la erally shifting the former. v

3. A vehicle wheel embodying a tireseating circumferential rim, a pair of tireretaining bands comprising broken rings positioned on opposite sides ofsaid rim, the outer portions of said bands formed to engage the base portions of a'tire and their inner lateral portions arranged to engage the beveled side faces of said rim whereby when said bands are shifted transversely toward each other the engagement between the engaging portions of said bands and rim will cause cont raction of the former, a pair of' annular clamping bands arranged to engage the-outer lateral faces of saidretainin'g bands, and means for drawingsaid clamping bands toward each-other for laterally shifting said retaining bands to contract the latter. E

4. A vehicle wheel embodying a .felly, a

gage the base portion of a tire and their inner lateral portions suitably formed to cooperate with the beveled portions of said rim to cause a contraction of the former and 'compression'of the base portion of a tire,

a pair of annular clamping bands arranged to engage the outer lateral faces of said retaining bands and adapted to draw the latter toward the said tire and simultaneously contract the latter, and a plurality of bolts extending through said clamping bands and said fellyjor' drawing the former toward each other.
